MACHINE FOR FORMING TOE-CLIPS ON HOBSESHOES.

[ all whom it may concern:

Be it known that I, FRANK H. W. Ronnrnnn, a citizen of the United States, residing at Indianapolis, in the county of Marion and State of Indiana, have invented certain new and useful Improvements in Machines for Forming Toe-Clips on Horseshoes, of which the following is a specification, reference being'had therein to the accompanying drawing. 7 p

This invention relates to a machine for forming toe-clips on horse-shoes and said invention consists in the mechanism hereinafter described in the specification and particularly pointed out in the claims.

The object of this invention is to provide a machine for forming toe-clips on horseshoes with facility and to construct said toeclips of a uniform size on like sizes of horseshoes. I attain these objects by means of the machine illustrated in the accompanying drawings in which like numerals of reference designate like parts throughout the several views.

Figure 1 is a vertical side view of the machine showing the toe-clip forming roller and the clamping plate in their upper portions; Fig. 2 is a similar view showing the clamping plate in position to grasp .the horseshoe, and the toe-clip forming roller in its lower position after having formed the toe-clip on the horse-shoe; Fig. 3 is a front vertical view of the machine looking in the direction of the arrows at in Figs. 1 and 2; *ig. 4 is an enlarged detail top sectional view of the anvil showing the gage-arms whereby the position of the horse-shoe is set relatively to the edge of the anvil and taken along the line 4-4 in Fig. 1; Fig. 5 is a detail end view of Fig. 4 looking in the direction of the arrow 6 in Fig. 4; Fig. dis a detail top sectional view of the machine taken along the line 66 in Fig. 3; and, Fig. 7 is an enlarged detail broken view of a portion of a horse-shoe and the toe-clip forming roller in its lower position about to move out of contact with the end'of the newly formed toe-clip of the horse-shoe. i

The anvil or table 1 of'this apparatus is constructed of a single slab of metal or steel which is supportedloy the tripod composed of the three legs 2 which are tied firmly near their bottom ends by the tie-rods 3 and the tie rods 4. On the top face of the anvil 1 are pivotally connected the opposing shoegages 5 to be moved longitudinally on the Specification of Letters Patent. Application filed. August 14,

surface of the anvil 1 and said shoe-gages are curved inwardly or toward each other to approximately fit around the curvature of a horse shoe when placed between them. Each of the gage-arms 5 is provided with a trigger lever 6 which is pivoted at its central portion to the standard 7 secured to said gage-arm, and a spring 8 is situated at the end of and between each of said triggers and the shoegages 5, and at the other end of each of said triggers is connected a latch pin 9 which pin is adapted to drop downwardly into either of-the gage-holes 10 when said gage-arm is moved to retain said shoe-gages in fixed position on the anvil 1 relatively to each other. The pressure plate 11 is arranged to move vertically toward and from the face of the anvil 1 and said pressure plate 11 is secured to the ends of the vertically extending guide-rods 12 which rods project vertically through the guide bores formed in and situated near the ends of the anvil 1 and the bores of the guide sleeves 13. The guide sleeves 13 project downwardly from the bottom side of the anvil. 1 and said sleeves are secured in position to said anvil, so thatthe bores of said sleeves register with the guide-bores formed in the end portions of said anvil, and said guide-rods extend vertically downwardly through the bores of said guide-sleeves to the cross-bar 14 to which said-guide-rods are secured at their bottom ends. 1

A; coil spring 15 is connected to the hook 16 secured to the bottom side of the anvil 1' and at its opposite end to the hook 17 secured to the crossbar 14,, so that the pressure plate 11 and the guide-rods 12 will tend to move upwardly to release the work engaged by said pressure plate, when the operator raises his foot from the treadle 18 of the foot lever 19 to release it. The rear end of the foot lever 19 is pivoted at its end to and between the bottom end portions of the vertical parallel bars 20. The eye 22 is connected to and situatedon the foot lever 19 and situated intermediate the treadle 18 and its pivotal pin 21, and situated centrally on the under side of the cross-bar 14 is a similar eye 28 which is engaged by the $-hook 24, so that the treadle 19 when pressed downwardly, the cross-bar 14 and the guide-rods 12 secured at their lower ends to said crossbars will be moved vertically downwardly to cause the pressure plate 11 to clamp the horseshoe and firmly hold it against the face of the anvil 1 between the guide-arms 5. The plunger-bar is composed of the rack bar having the rack teeth 26 adapted to be en gaged by the teeth 27 of the mutilated gear 28. The mutilated gear 28 is pivotall 1 mounted, between the vertically extending bars 20, on the pin 29 extending through and supported at its ends by said bars. lne top ends of the vertical bars 20 are held in position by the tie-bars 30 which are securely bolted at their rear ends to the top ends of the bars 20, and at their forward ends to the top ends of the bars 31, which latter bars project downwardly and backwardly toward the vertical bars 20, to be secured at their lower ends to said latter bars.

The teeth 26 of the rack bar 25 are held in engagement with the teeth 27 of the muti lated gear 28 by the guide pulley 32 pivoted on the pin 33 secured at its ends in the end portions of the bars 30 and 31. Projecting downwardly from the lower end of the rack bar 25 are the parallel depending bars 3st which are firmly secured to the lower end portion of said bar 25 and situated in parallel relation to each other and between the bottom end portions of said bars 34: is situated the forming roller 35 which roller is pivoted on the pin 36 at its ends in the end portions of the parallel bars 34. The third bar 37 is secured at its top end to the bottom end of the rack bar 25 and projects downwardly therefrom a short distance below the roller 33 and the front surface of the said bar 37 is situated so as to clear the periphery of the forming roller 35 and the back surface of said bar is adapted to contact with the guide roller 88 pivoted on the pin 39 secured at its ends in the vertically extending frame bars 40, and said roller 38 is provided to form a friction bearing against which the depending bar 37 rests to rigidly maintain said forming roller 35 firmly against its work. The actuating lever l1 is secured to the mutilated gear 28 and the same is provided for the purpose of revolving said mutilated gear to operate or move the rack bar 25 downwardly. A coil spring 4:2 is connected at its upper end to the eye bolt 43 secured to the end of the actuating lever 4C1 and at itsopposite end to the eye bolt 44 secured in any suitable way to the bars 20. The frame OOnsists of the vertically extending bars 20 and and the angle bars 30 and 31 are supported by the horizontally extending bars as which are secured at their forward ends to the end surface of the anvil l and at their rear ends to the bars 20.
